 # Chemistry-Revision
 Just something for me to practive chemistry <br>
+A tool to help with memorising the first 30 elements of the periodic table as well as some common polyatomic ions.<br>
+Whether certain proterties are assessed can be toggled. Useful when you don't want to have to memorise the molar mass of everything for example.<br>
+Beware of jump scares when questions are repeatedly answered incorrectly.<br>
 For the atomic mass and valencies, you can answer 'IDK' to skip them if they are too difficult or irrelevant.<br>
 The Failure and Stooid memes are by Steven He and the brain images were take from a random brain expanding meme.<br><br>
